New hardwood was installed on a home I am buying. It is 'Lifescapes' light grey oak wire-brushed hardwood. It has a very natural look (looks like they just cut a bunch of pine and just placed it on the floor). It's very pretty, but really doesn't look like it's complete. Can anyone tell me if it is supposed to have a varnish/finish applied to it, or is it just supposed to have a raw look? Also, if it is the way it should be (unfinished), how do I clean it? I was told to just use warm water, but I have two small children that spill things. What if they were to spill a glass of red kool-aid? Will the red seep into the wood, or will it wipe up?
